84 kq locking diffs

Let's start with a refresh of the original quattro system. It had 3
diffs - front, rear and center. The front is never lockable, since
that impedes steering. The center and rear are lockable. The rear
only below ~20 mph and intended only for extreme conditions - like
stuck. The center diff could be run at any speed (and I did) and could
be locked to avoid fishtailing, etc. With it open, the car could be a
handful in the snow.
So you will never lock the front diff.
And you dont want to lock the rear until all other options are
So it works just as you want it to, if I understand you properly.
